DENVER (KDVR) — The Wyoming State Capitol in Cheyenne was evacuated Tuesday morning due to a “report of a suspect IED,” state officials said.

The Wyoming Highway Patrol just before 11 a.m. Tuesday said in a Facebook post that the building was evacuated as the agency investigates an “ongoing incident.” The agency at 12:07 p.m. said it is investigating the report of a suspected Improvised explosive device, or IED.

“The building was evacuated quickly and safely as a precaution,” WHP said. “A multi-agency, precautionary response is underway involving the Wyoming Highway Patrol, Laramie County Sheriff’s Office, Wyoming DCI, Cheyenne Police Department, and the Joint EOD Team, as well as federal agencies.”

WHP did not say what the incident was, but local media outlet WyoFile reported legislative officials said the evacuation was due to a suspicious package being discovered.

WyoFile also reported Wyoming Gov. Mark Gordon was in the building when the evacuation was ordered.

WHP asked people to avoid the area during the investigation and said there is no timeframe for an estimated return to the capitol.
